Here's Jody's plans for me-go-faster--
"For the E-350 I would go with the F5 chip/switch and get stock, 60hp tow, & 80hp econo"
"For the F-350 I would go with the F5 chip/switch and get stock, 40 or 60hp tow (depend upon tow weight), & 80hp econo"
I think I'd like to add an "insane fast/lots of smoke" 4th setting for the F-350... **grin**
I like the air filer set up you're working on... will you have to fab the "t" yourself, or is there a ready made one availble? What filters do you have? Looks cool, but is it really more surface/filtering area than the orig 2 flat filters? Or is the fact that the filters arn't inside a restrictive housing the advantage? Just looking at the pictures, the filters don't look grossly larger than the orig, (mine has 2 flat type filters, 2x the size of the stock one on my superduty, which was overwhelmed by the size of the WIX 46637 (tymar/DIY) airfilter that replaced it) the two you have seem to only offer about the same square inches of filtering area. However, I do not have both of them infront of me like you do, and you would be a better judge of the compairablity. As time permits, I want to do something like you are with my van... thanks for the pic's.
